Dwarf/no growth in Spring

Asked May 31, 2019, 1:47 AM EDT

We have 32 rose bushes that have not developed any growth this Spring. Initial buds developed into very tiny, wrinkled leaves. Many are now appearing dead but others show signs of life but only these tiny malformed leaves. The bushes are in various locations in the yard so it is not isolated to one bed. There are two bushes that have some normal growth mixed with the other previously described growth.

Thank you for your (10) questions. Here is a WSU Extension article with a comprehensive list of rose problems: http://cru.cahe.wsu.edu/CEPublications/FS246/FS246E.pdf However, the growths in the photo appear to be that of the rose rosette disease, not yet found in PNW articles, but described here: https://www.pubs.ext.vt.edu/content/dam/pubs_ext_vt_edu/450/450-620/450-620_pdf.pdf Please take your photos and plant samples and visit your county Extension office: https://extension.wsu.edu/thurston/ so staff can give you a firm diagnosis and advice. Good luck!
